UNITED STATES BENJAMIN F. JOHNSON, OF CLEVELAND, OHIO.

PIPE.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed September 22, 1919. Serial No. 325,349.

T 0 all whom it may concern Be it known that I, BENJAMIN F. JoHN- SON, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Pipes, of which the following is a full, clear, and exactdescription.

The present invention relates to toh cco smoking pipes, and seeks toprovide a construction which provides a well for the collection ofsaliva which may pass into the pipe from the mouth of the user andprevent the fouling of the pipe.

A further object is to construct a pipe as aforesaid, which may beeasily cleaned.

A further object is to provide a construction for the purpose w iichwill add little or no weight to a pipe and further, the construction issuch as to add very little extra expense in the manufacture.

Generally speaking, the invention may be said to comprise theelementsand the coinbinations thereof, set forth in the accompanying claim.

Reference should be had to the accompanying drawings forming a part ofthis specification, in which Figure l is a sectional elevation of a pipeembodying my invention; Fig. 2 is a section upon the line 22 of Fig. 1;Fig. 3 is asection upon the line 33 of Fig. 1-, Fig. 4 is a section uponthe line l-l of Fig. 1; Fig. 5 is an elevation with portions in sectionof a portion of the pipe.

As is well known, a pipe in use collects more or less saliva which findsaccess to the stem and bowl of the pipe forming objectionable fouling.

In the present invention, 1 indicates the bowl of the pipe and the shortstem usually made integral therewith is indicated at 2.

The stem which has the mouth piece, is indicated at 3 and may be madeusua ly constructed or as I prefer, it may be made to have a straightunderside.

The two parts of the pipe, to wit; the bowl stem 2, and the mouth stem3, are join d by a member 5. As shown in the drawing, this member has acentrally disposed projection 6, against which the ends of stems 2 and 3may engage, while the portions of this member 5 on opposite sides of theprojection 6 extend into the stems 2 and 3, having a snug fit whicheffectually serves to unite the three parts together.

The member 5 has formed, in which may be termed the top part thereof, agroove 7, which groove is open at the top except for a short distanceupon both sides of the central projection 6. This portion of the groovejust referred to is indicated at 8 and the construction insures thatthere will be no leak at the joint where stems 2 and 3 en gageprojection 6, a leak being very undesirable because of its effect on thedraw of the pipe.

The provision of a construction with an open groove like groove 7 isadvantageous as it permits the groove to be easily cleaned ofaccumulated tobacco dust drawn back from the bowl in the use of thepipe. Furthermore having the groove 7 at the top of the member 5provides a larger space in the mouth stem 3 for the accumulation ofsaliva, and in the stem 2 for tobacco dust and ash dust which may passthrough the dust which connects the bowl with the stem :2.

The accumulated moisture in stem may be discharged by inserting the pipewith stem 3 down, or the stem may be removed.

At the end of the member 5 which is within stem 3, the groove 7 isdirected downwardly atright angles, as indicated at 7 and opens into acup shaped portion at the end of the member This construction is moreeffective in preventing the entrance of collected saliva, into groove 7than if the groove merely extended straight, to the end of member 5.

As will be seen, the general appearance of the pipe is not materiallychanged from the conventional shape and further, the use of the member 5does not require a bulky or heavy construction for the pipe.

The construction is simple and the cleaning of the pipe is perhapsmoresimple and easier than the usual pipe.

Having described my invention, 1 claim: A pipe having a bowl with ashort hollow stem. a mouth stem of hollow construction, a joining membercooperating with both of said stems. said member having an open groovein the upper portion thereof, one end of said groove being closed and adownwardly directed opening cooperating with the groove at the closedend.

In testimony whereof, I hereunto affix my signature.

BENJAMIN F, JOHNSON
